This is a demonstration of a PCB repair which involves repairing damaged surface mount solder pads as well as cleaning up corrosion from a leaking electrolytic capacitor. The pads had been damaged by the owner of the motherboard as a result of him trying to repair the board on his own.
I hope that this video will give you some ideas on how to perform a proper pad repair using the epoxy method.
During this repair, I used an epoxy that is heat resistant up to 315°C for 60 seconds.
If you ever find any kind of epoxy on the market that is specified to be heat resistant up to more than 315°C, then I would be happy if you could let us know about it in the comment section as it does appear that high temperature epoxies are quite difficult to find.
The following products was used in this video:
CircuitWorks CW2500 – Two component epoxy overcoat
CircuitWorks CW3300 – Overcoat Pen
I have made several videos before where I have had to fix up other people’s mistakes that they have made during their repair attempts, and this repair only adds on to the list.
If you are not a repair technician and your motherboard has stopped working, it would be in the best of your own interest not to attempt a repair that you really cannot handle. Because there is a huge risk that you will actually end up doing more harm than good. We are of course mostly talking about board damage in the case of motherboards, but it gets considerably worse when dealing with things like power supplies, which can easily become a great shock hazard to inexperienced technicians and even result in electrocution.
As always, comments and questions regarding this repair are always welcome.
